  • Pass
    Lists tools

    tools/list returned 4 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 688 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 688 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Pass
    Parameters documented

    12 of 14 parameters have a description (86%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Pass
    Website matches publisher

    The website host matches the reverse-domain namespace.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

find_anchorages

Lists the places near a position where boats stopped, overnight or by day, with where boats stayed in tonight's forecast there or in a given wind. For tonight, call it without wind_from and wind_kn: the answer then carries tonight's forecast at the position and each place's nights in each of tonight's winds, as the site's Tonight does. Give a wind only to ask about that wind. Each place comes with how far and which way it lies from the position (e.g. 0.5 NM SW), its nights, where it is, its page and its place on the map. With a wind, each place gets its nights in that wind, split by strength, with the gusts on those nights (kt), and the list is sorted by those nights. A wind is counted as the site counts it: its compass point at 10 or 20 kt or more, as the forecast's band (e.g. wind_kn 15 counts E 10 kt or more). wind_from alone counts the direction at any strength. Under 3 kt (wind_kn in whole knots) the wind has no settled direction, so every night counts. A night counts once, in the wind it blew from most. Tonight is counted as the site's Tonight counts it: tonight's forecast times that are night there, each counted in its compass point at 10 or 20 kt or more, as its band (every night under 3 kt), and each place's fewest nights in any one of them. Where a place faces open water and tonight's swell there is 0.5 m or more, the nights of that count that also had that swell are given beside it, as on the site. The swell never changes the count. Places with a night in every one of tonight's winds come first, by those fewest nights, then the rest. Without a forecast, by distance. Positions are WGS84 decimal degrees.

Discovered
get_bay_evidence

What boats did at one place, as its page on the site shows it. Its nights. Its nights by the eight compass points the wind blew from, split under 10, 10 to 20 and 20 kt or more, with the different boats and the windiest night of each. Its boats by length and type (cells under 3 boats null), its day stops by wind, its nights by swell direction where its page shows them, and the places nearby with how far and which way. It carries tonight's forecast at the place: the night's strongest forecast wind and the place's nights in that wind, as its page's Tonight shows it. Give bay_id, or name with near (WGS84 decimal degrees) to rank places of one name. Several places of one name come back as candidates.

Discovered
get_climatology

Wind through the year at a place, as its page shows it: for each month, the nights whose strongest hour reached 20 kt and 30 kt, each year's fewest and most of them, the commonest directions of the nights of 20 kt or more, and the strongest gust, over ten years, for the area round the place. The first call for an area can answer preparing, then ready a few minutes later.

Discovered
list_regions

The site's directory of places where boats stayed the night. Without a country: each country with its number of places. With a country (directory slug or ISO code): its regions and cruising areas with their number of places. Each with the address of its directory page.
